Cat Deeley Says She's 'Just Going to Wing' a Very Important Part of Welcoming Baby No. 2 (Exclusive)

ET's Deidre Behar spoke with the expecting star at the Los Angeles auditions for season 15 of So You Think You Can Dance on Wednesday, where she opened up about preparing to welcome baby No. 2 -- and revealed which important part she's planning to "wing!"

"I'm feeling pretty good, apart from the fact I need to pee constantly," she joked. "I'm like, 'OK, where is my nearest Starbucks or Whole Foods?'"

"I'm all good," she continued. "I love doing this show, so it isn't work for me. It's just quite nice to see everybody again, and have a good time."

The 41-year-old host is already mom to 2-year-old son Milo, but said he still doesn't know he's going to be a big brother. "I want to tell him when it gets a bit closer and he can get excited and understand it, but right now, he doesn't even notice, actually," she explained. "He's got something to lean on right now, when I read him stories. He can cuddle it, but he hasn't said anything. He hasn't gone, 'Mom, sort it out!' He's good."

Deeley and her husband, Patrick Kielty, are also waiting to find out if they're having a boy or girl until she gives birth in a few months -- and to pick out the little one's name.

"We never agree on names, my husband and I, so we're just going to wing it!" she revealed.

"I think I will always win at the end of the day, because I've done all the hard work," Deeley added of picking a name. "So I'm just not going to say anything. Let's not argue about it right now. I'll just win when it comes up, right?"

And while Deeley is expanding her family, she couldn't be happier to be reunited with her SYTYCD one.

"It's family," she gushed. "That's it, when it comes right down to it... nobody goes away, no doors are closed. It's always like, everybody comes back, we go to people's weddings, we see people's children. We are the the biggest, most phenomenal, dysfunctional family known to man."

"We're like Christmas decorations that you made when you were two. You just dust them off and then put them back into a tree!" she added.

Season 15 of So You Think You Can Dance returns Monday, June 4 at 8 p.m. ET/PT on Fox. See more from the show's LA auditions in the video below.
